Renshato:

  • Orbital Distance:  N/A AU
  • Orbital Period:  0.5 Earth-years
  • Keplerian Ratio:  N/A
  • Radius:  25,957 km
  • Day Length:  18.1 Earth-hours
  • Atmospheric Pressure:  N/A atm
  • Surface Temp:  N/A °C
  • Surface Gravity:  N/A g
  • Mass:  N/A Earth-masses

Renshato is close-orbiting “Hot Jupiter” with traces of sulfur in its hydrogen-helium atmosphere. The disruptive gravity well of the gas giant prevented any planets from forming nearby.

Trivia
Renshato is too small (and hot) for a “hydrogen-helium atmosphere” to define it (William Hubbard, The New Solar System 4th ed, 1999; p. 194). It is more likely a dense “ice giant” like Neptune or Gliese 436 b.

Binthu:

  • Orbital Distance:  N/A AU
  • Orbital Period:  5 Earth-years
  • Keplerian Ratio:  N/A
  • Radius:  5,935 km
  • Day Length:  53.2 Earth-hours
  • Atmospheric Pressure:  0.91 atm
  • Surface Temp:  94 °C
  • Surface Gravity:  0.94 g
  • Mass:  0.808 Earth-masses
  • Satellites:  1

Binthu has an atmosphere of carbon dioxide, with a permanent haze of toxic chlorine and clouds of sulfur dioxide that periodically drop torrents of acidic rain on the surface. Its crust is mainly composed of sulfur with deposits of calcium.

Like most worlds in the Voyager Cluster, Binthu has only been charted within the last 20 years by Alliance surveyors. It has no known native ecology. Data about the world is surprisingly brief and generic, painting a picture of an unpleasant and uninteresting place.

Dregir:

  • Orbital Distance:  N/A AU
  • Orbital Period:  23.7 Earth-years
  • Keplerian Ratio:  N/A
  • Radius:  2,843 km
  • Day Length:  34.0 Earth-hours
  • Atmospheric Pressure:  0.00 atm
  • Surface Temp:  −96 °C
  • Surface Gravity:  0.28 g
  • Mass:  0.055 Earth-masses

Dregir is a small, barren rock world with a trace atmosphere of krypton and xenon. The surface is frigid, and mainly composed of silicates with deposits of magnesium, aluminum, and other light metals. Dregir has a weak magnetic field, making it unsuitable for drive discharge operations.

Alrumter:

  • Orbital Distance:  N/A AU
  • Orbital Period:  35.2 Earth-years
  • Keplerian Ratio:  N/A
  • Radius:  3,718 km
  • Day Length:  39.5 Earth-hours
  • Atmospheric Pressure:  0.00 atm
  • Surface Temp:  −96 °C
  • Surface Gravity:  0.39 g
  • Mass:  0.132 Earth-masses

Alrumter is a small, rocky terrestrial planet with a trace atmosphere of nitrogen and krypton. Its frigid surface is mainly composed of light metals with deposits of frozen ammonia.

Survey Text
“You detected a weak signal coming from the far side of the planet Alrumter. Joker brought the Normandy around and your salvage team picked up a small escape pod trapped in orbit. There was a long-dead turian inside along with a few personal items and a Prothean data disc.”

Patajiri:

  • Orbital Distance:  N/A AU
  • Orbital Period:  123.6 Earth-years
  • Keplerian Ratio:  N/A
  • Radius:  7,304 km
  • Day Length:  57.7 Earth-hours
  • Atmospheric Pressure:  0.42 atm
  • Surface Temp:  −118 °C
  • Surface Gravity:  0.99 g
  • Mass:  1.289 Earth-masses

Patajiri has a thin atmosphere composed of neon and chlorine. Its frozen surface is mainly composed of silica with deposits of copper. During the long, cold night, the chlorine in the atmosphere falls to the ground in the form of frost.
